HARROW.

SPECIFICATION forming part of Letters Patent No. 328,519, dated October 20, 1885. l Application iiled April 27, 1885. Serial No. 163,631. (No model.) l

To all whom, t may concern.-

Beit known th at we, ALBERT H. PRICE and WALTER D. PRICE, citizens of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Harrows, of which the following is a specification.

Our invention relates to improvements in folding harrows; and it consists in the various constructions and combinations hereinafter described, and pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a'perspective of a harrow embodying our invention,shown folded up ready for transportation. Fig. 2 is a plan view of the same unfolded and ready for use. Fig. 3 is a side elevation view .of the same, showing the lifting levers; and

Figs. 4, 5, and 6 are detailed views of some of the parts, which will be more particularly referred to hereinafter.

Like parts are indicated by similar letters of reference throughout the several views.

The harrow is composed of the rectangular or square sections A B B', which are connected together, as shown, by the hinge-connections C. On the outer edges of the side or wing sections B and B', respectively, are runners or supporting-bars D D, on which the harrow is supported when folded up, as shown in Fig. 1. The hinged connections O each consist of an arm, a, which is secured at one end to the edge of the middle section, A, and projects outwardly, and is connected to a bifurcated clip, b, which is secured to the inner edge of the wing-section. The joint or hinge is preferably made by means of a rod, c, which extends through an opening in the end of said arm and through the clips b. The connection thus formed permits the win g-sections to turn ninety degrees from the horizontal, or at right angles to the middle section, but is limited against further movement by the connectingarm a coming into contact with the base of the bifurcated clip b, as shown in Fig. 6.

In order to provide for raising the respective sections, as desired, to remove any dbris which may collect therein, or for other 'purposes, we provide lifting-levers E E,which are supported on the middle section, A, and connected by suitable means to the side or wing sections, B B. These levers are each connected at one end to a standard, F Fp', at the front of the middle section by means of a slotted connecting-piece or yoke, d. The standards F F have each an elongated head, e, adapted to pass through thev slotted piece or yoke d, when said yoke is turned parallel thereto, as indicated by dottedlines in Fig. 4, said yoke being held from coming .offfof said standard by the elongated head when turned to its normal position, as shown in full lines in Fig. 4. The levers E E extend backwardly from the standards F F, and are supported at the rear of the harrow in bifurcated supports G, which middle section, A.

The fork projections f fof the bifurcated standards or supports G are each constructed in the form of a hook, and are adapted to be project upwardly from the engaged when the lever is raised vertically v therein by a projecting pin or pins, g, secured in the lever. (See Fig. 5.) The projecting pins g are so placed in the lever E that when the lever is in its normal position in the support G the said projecting pinsstand below l the point of the hooks in projections ff, so that by a longitudinal movement of the said lever the pins may be movedfrom under said hooks, and thus permit the lever to be raised out of the supporting-piece Without engaging said hooks. This longitudinal movement of the lever is permitted by the slotted piece or yoke d, by which it is connected to standard F.

The levers E E are respectively connected, preferably by means of chains H H', to the side sections, B B, as shown, so that when either of said levers is raised out of the supporting-piece G, as indicated by dotted lines in Fig. 3, the section connected thereto may be readily raised from the ground and turned on its hinged connections by a lateral movement of the said lever.

If it is desired to raise the middle section the levers are dropped into the bifurcated supports and moved longitudinally forward until the projecting pins g come under the hooks on the fork projections ff, when, by a vertical movement of the levers, the pins g will engage said hooks, and thus raise the harrow.

When it is desired to fold the harrow for transportation. the harrow is raised up on its IOO front end, the chains H H unhooked from the lifting-levers, and theside or wing sections turned in at right angles to the middle sections, after which the inner ends of the chains H H are attached to hooks h h at ther middle of the middle section, A. The harrow is then turned over onto the runners D D', the hitch is made to rings i fi', secured to the edges of sections B B', at the front ends of runners D D', and the harrow is ready for transportation.

It will be seen that by making the sections square or rectangular, as shown, and folding the side or wing sections inwardly, as described, the middle section will be elevated equally at both ends to a distance from thek ground equal to the width of the side sections,

. so that it may readily pass over ordinary obstructions without danger to the teeth of the harrow. f

The hinged or side sections are held from turning inwardly by the hinged connection,

as described, and from turning outwardly by `the chains H H. The teeth being all turned inward are protected from injury, and at the same time are less dangerous tocattle or stock when theharrow is left vstanding in the field.

Byhaving the side sections to fold inwardly at right angles to the middle section' we are enabled to place the metallic runners D D on the outer edges of the side sections and in the same horizontal plane therewith, thus leaving the-top of 'the' sections free, and at the same timey bringing the weight of the runners or supports where it is most needed.

The lifting-levers, it will be seen, are a tached to and supported entirely from the middle section, so that they need-not be disturbed or changed when the harrow is folded. They are at the same time readily detachable, and

may be removed or replaced at will.

Having thus described our invention, we claimy 1. The combination, in afolding harrow,of

a middle section having side or wing sections hinged thereto, said side or wing sections being rectangular in shape and provided on their outer edges with supporting-runners on which the harrow is adapted to rest by folding said side sections inwardly at right angles to the middle section, and thus raise said middle section equally at both ends for transportation, substantially as specified.

2. The combination, with the lifting-lever -`provided with the slotted connecting' piece or loop and with a projecting pin or pins, of the standard havingan elongated head and the bifurcated support having hooked projections, and means for connecting said levers to the movable or 'hinged section, substantially .as set forth. V

3. The combination, with the middle and side sections, of the lifting-lever'adapted to be connected at one end by a slotted connecting piece or loop to a standard provided with` an elongated head on said middle section, a support for the rear end of said lever, and means for connect-ing the said levers to the side sections, substantially as described and shown.

4. The combination, with the stationary middle section having the lifting-levers thereon, of hinged movable sections having chains connected to the outer edges thereof, said chains being adapted to be connected to the said levers when the harrow is unfolded and to the middle section when the ha'rrow is folded, substantially as and for the purpose setforth.

In testimony whereof we have hereunto set our hands this 16th day of April, A. D. 1885.
